In Mrs. Swizz Beatz's defense, she had been tweeting from her BlackBerry, but it seems like the iPhone might be her personal phone. The Apple device is definitely her side piece, if not her number one gadget, despite that awkwardly long metaphor she made on stage last month about breaking up with iOS at the launch of BlackBerry 10. Perhaps two weeks in, she got sick of the Z10 and said screw it. No one likes a cheater, Alicia.
